Weapon with lock or manual safety device

ABSTRACT

WEAPON WITH A LOCK OR MANUAL SAFETY DEVICE, with a manual lock that, when engaged on safe position, blocks (intercepts) the path of the hammer, thereby preventing it from hitting the firing pin.  
     The manual lock  24  is made up of a cylindrical part axis  14  with a recess  10 , connected to a latch  2 , with a semicircular slot  9 , two blind holes  8 , in which a sphere  12  lodges, inserted together with the spring  11  in the blind hole  5  of the receiver of the weapon  3  and a stop pin  7  placed in the hole  6  of the receiver of the weapon  3  fitting in the semicircular slot  9  of the latch  2  of the manual lock  24 , the hammer  1  having the detail  13  that can be blocked (FIG.  7 ), by the cylindrical axis  14  of the manual lock  24 , or, can be lodged on the recess  10  of the cylindrical axis  14  of the Manual lock  24.

TECHNICAL FIELD OF THE MODEL

The following description of the utility model refers to the development of a weapon with a lock or manual safety device designed for blocking the complete path of the hammer through a mechanical interception, thereby avoiding any contact of the hammer with the firing pin of the weapon, in order to avoid accidental discharges.

STATE OF TECHNIQUE

The weapons currently known have an intrinsically safe mechanism whereby the hammer does not hit the firing pin and the cartridge primer whenever the trigger is not voluntary operated (pulled all way to the rear).

This type of safety is good enough for cases in which the hammer is knocked or smashed, whenever the weapon is dropped accidentally or for any other reason.

However, this type of safety is not valid whenever the trigger is voluntarily operated (like during the manual hammer decocking operation with a live round on the chamber).

The research conducted on the state of the art enabled us to select the following patent document of a safety device applied in a firearm. We therefore have:

PI 0.201.686, registered on May 9, 2002, under the title MECHANICAL SAFETY DEVICE FOR FIREARMS, referring to a mechanical safety device that has been perfected for firearms such as hunting rifles equipped with a safety device at the grip, under the gun barrel, in which the safety device includes at least one safety pin or rod (11) that can be moved axially from an active position that disables the use of the firearm to an ‘inactive’ position that enables the use of the firearm; and which has along with this safety pin, at least one selecting spring-loaded element (13 and 14) which defines the active and inactive positions of the safety pin alternately and is characterized by a safety body revolving around a geometrical axis that intercepts the direction in which the safety pin is moving between the locking position of the safety pin so as to check its movement from the active position to the inactive position, and the unlocking position of the safety pin so as to enable the active position to become inactive, the safety body being thereby activated through a specific control key.

SUMMARY OF THE MODEL

So, due to the pertinent considerations concerning the state of the art specified here above, this description of the utility model deals with the development of a weapon with a lock or Manual safety device that has a manual safety lock that was designed for blocking the total path of the hammer through a mechanical interception, thereby avoiding any contact with the firing pin of the weapon and avoiding it to be pushed against the cartridge primer through any voluntary or accidental action.

ASSEMBLING THE MANUAL LOCK AND FUNCTIONING

After assembling the mechanism onto the receiver of the weapon 3, which is made up of the hammer set 1, the firing pin set 21, the transfer bar system 22, the trigger set 23, and fixing the limiting pin 7 onto the receiver of the weapon (detail 6), proceed to assembling the safety device by placing the axis 14 of the manual lock 24 in the hole 4 of the receiver 3 (on the right side) with the spring 11, and the sphere 12 of the manual lock 24 by inserting them in the hole 5 of the receiver of the weapon 3. Then, assemble the safety latch 2 (detail 27) in the axis 14 and place the fixing pin thru the pin's housing holes (detail 26, and 28);

This assembling procedure will enable the manual safety device (manual lock) of the weapon to work perfectly. Placing the latch 2 of the manual lock 24 in a fire position (“F” 16 been visualized) will enable to fire the cartridge after executing the firing sequence, in other words, when in a cocked position as shown in FIG. 2, pull the trigger 23 and hold it until the hammer reaches the position shown in FIG. 1.

Placing the latch 2 of the manual lock 24 in the safe position (“S” 17 been visualized), the weapon will not fire when you execute the firing sequence, in other words, when in a cocked position as shown FIG. 2, pull the trigger 23 and hold it, and the hammer's path will be intercepted by the manual lock 24 show in FIG. 3.

When the weapon is in cocked position shown in FIG. 2, and the shooter quits to fire, place the latch 2 of the manual lock 24 in the safe position (“S” 17 been visualized), pulls the trigger 23 and, while holding the hammer 1 with your thumb, brings it to the intercept position of FIG. 3, thereby avoiding any accidental contact with the transferbar 22 and the firing pin 21. In this position, the hammer 1 is intercepted (FIG. 3), the weapon action can be opened and the cartridge may be withdrawn with total safety.

Description of the Preferred Form for the Design and Construction of this Model

Lock or Manual safety device capable of intercepting or blocking the path of the hammer 1, characterized by a part named manual lock 24, assembled on the receiver of the weapon 3, and able to be moved manually in two distinct positions clearly defined by the blind-positoning holes 8 of the manual lock 24 (where the sphere 12 lodged); for each position of the manual lock 24, it's possible to visualize either the letter “S” 17 or “F” 16, which enables, respectively, to intercept the hammer's path (FIG. 3), or not, leaving the weapon ready to fire (FIG. 1) thanks to the hammer stop 13 which can be intercepted by the axis 14 (FIG. 7 safety position) or lodged on the recess 10 of the axis 14 (FIG. 5 fire position). 

1- WEAPON WITH A LOCK OR MANUAL SAFETY DEVICE characterized by the fact that it has a manually operated lock that, when engaged, intercepts the hammer's path and blocks it before it hits the firing pin. 2- WEAPON WITH A LOCK OR MANUAL SAFETY DEVICE as per claim 1, represented by a part named manual lock 24, assembled onto the receiver of the weapon 3, which can have two distinct positions clearly limited by blind holes 8 on the manual lock 24, in which the sphere 12 lodges. On the receiver 3 also can be seen the letters “S” 17 and “F” and 16, which enables respectively, the blocking (FIG. 3) of the hammer's path by the hammer stop 13 when it's intercepted by the manual lock 24 in the safe position (letter “S” visualized), or not, (FIG. 1) in case the hammer stop 13 is lodged into the recess detail 10 of the manual lock 24 in the fire position (letter “F” visualized). 3- WEAPON WITH A LOCK OR MANUAL SAFETY DEVICE as previously claimed and characterized for having a latch 2 and a recess 10 on the axis 14, two blind holes 8, one semicircular slot 9 on the latch 2, which, through a mechanical action (finger pressure), changes from position “S” 17 to position “F” 16 (or vice-versa), thereby enabling the blocking (interception), or not, of the hammer's path.
